Abstract:
A transmissive optical device comprising: a layer (10) of light absorber material in the solid state, preferably made of a phase-change material with switchable refractive index such as GeSbTe; a partially-reflective layer (12), and a spacer layer (14) between the layer (10) of light absorber material and the partially-reflective layer (12). The spacer layer (14) and an optional cover layer (16) may be transparent conductive ITO layers which may serve to electrically switch the phase of the phase-change material layer (10), thereby switching the transmission/reflection properties of the transmissive optical device.

Abstract:
The present invention provides for improved contrast in the transmissive mode of a transfiective liquid crystal display having a rear stack polarizing means (302) which is transmissive for light having a desired polarization and reflective for light having an opposite, undesired polarization. The contrast is improved due to enhancements of the black state provided by the inclusion of a reflection preventing means (306). The reflection preventing means is arranged between the transflector (301) and the rear stack polarizer (302), and serves to stop light transmitted through the rear stack polarizer (302) towards the transflector (301) from being reflected by the transflector (301) back to the rear polarizer (302). Thereby undesired reflections having wrong polarization are stopped from being transmitted through the transflector (301) and thus from affecting the transmissive mode black state of the display.
